The snippet below shows a basic example of how theInfiniteLoadercan be used to wrap either aFixedSizeListorVariableSizeListfromreact-window. // This value is arbitrary.// If you know the size of your remote data, you can provide a real value.// You can also increase this value gradually...
Basic the idea here is to set the ref from react-custom-scrollbars so the react-window AutoSizer or VariableSizeList will work with this approach, as in this example https://codesandbox.io/s/react-window-custom-scrollbars-t4352 @ranihorevcan you also share Code Sandbox example?
从官方的 Demo 来看,AntD 提供了一个 components 属性,通过传入一个对象,在其 body 属性中给到一个 ReactWindow 提供的虚拟化组件,以实现需求 ... // VariableSizeGrid is a component provided by react-window const renderVirtualList = (rawData, { scrollbarSize, ref, onScroll })=> <VariableSizeGrid...
